Fifteen years in backend engineering, the last eight on payments and ledgers. I led the team that rebuilt a card-processing pipeline handling eleven million transactions a day, and I've been on the wrong end of enough incident reviews to know which shortcuts cost you later. I'm useful if you're designing a ledger, choosing between Stripe and a processor-direct integration, or trying to figure out why reconciliation never matches. I review architecture docs and code with equal enthusiasm.
